It has a fair resolution and is a .mp4. It uses about the same amount of CPU power as Smplayer. I can't tell any difference even with the same video. It appears that it may be something besides the player. I did find some settings tho. I also figured out how to tell it to send sound to the TV. Progress. ;-) Any other ideas? Something just don't seem to be working right here. Dale :-) :-)

Also the proprietary one is way faster for gaming. I'm using nvidia. I meant to include that in the first post but forgot. Age. :/ [IP-] [ ] x11-drivers/nvidia-drivers-396.54 I can't recall the exact FPS before with old card but I'm thinking it is somewhere close what I'm getting here. Plus the CPU usage makes me wonder. While I don't do gaming, I still want the video card to do its job. After all, that's what it is there for. When I'm doing updates in the background, that takes away from that if Smplayer/mplayer are using a lot of CPU power. At least it isn't just me that thinks the card isn't getting the load it should.

Plus, I have to tell Smplayer to send audio to the TV not the computer speakers. I have no idea how to do that in VLC. May google that at some point. Still, just didn't like VLC much. I'm using the nvidia drivers. Info. [IP-] [ ] x11-drivers/nvidia-drivers-396.54 I meant to include that in first post but forgot. Ooops. Thanks. Dale :-) :-)

You should avoid SMPlayer (IMHO from my experience at this point) and switch to mpv or VLC. You want to enable hardware decoding with VDPAU with any player. That card can decode H.264 fully and partially can decode MPEG-1/2/VC-1. You will see very little CPU usage with VDPAU enabled.

[gentoo-user] Playing video and CPU usage
Howdy, As some know, I recently bought a video card. While not the most modern thing, it is a lot faster than my old one. I have a question tho. When I'm watching TV and playing a video with Smplayer, high resolution or a medium resolution, it seems to use a good bit of CPU power. I notice in gkrellm, htop etc that it is using about 20 to sometimes 40 or 50% of CPU power. Yes, I still have the 8 core CPU in here. In Smplayer, I have video driver set to "gl(fast)" but have tried other settings as well. Obviously, some just plain don't work at all. It causes Smplayer to crash. I did some googling, I think this is the best driver setting for my card. It is nvidia based. Question, how do I know it is using the video card to process as much of the video as it is supposed to be doing? Is there some command I'm not aware of to test this?

[gentoo-user] systemd-240 doesn't load my kernel modules
Hi, I have systemd and openrc installed on my system, but I use openrc for booting. Upto systemd-239 this works just fine. But with systemd-240 my system doesn't load necessary kernel modules like DRM AMDGPU modules. This break Xorg : (EE) open /dev/dri/card0: No such file or directory Has anybody an idea what is different under systemd-240 in comparison to systemd-239? Many thanks for a hint, Helmut
